Title: Bouquet presentation device
Inventor: CHARRIN PHILIPPE
IPC: B65D85/50
Filed: 1996-05-23
Abstract: The invention provides a variable shape device, with or without a base, for presenting all types of bouquets individually, vertically and without water. The device (1) is made of water- and deformation-resistant materials, with an adjustable attachment means having a male (3) and a female portion (4). The assembled device has a tapered portion (5) with tabs (11), which adapts to every type of bouquet, and a stable base (2). The openings (6) enable the bouquet to be initially retained in the device, for individual presentation, by any fastening means inserted in the openings. A  water-tight decorated sheet (8), extending towards the top (5) of the outer walls (1) and adhering to members (7), is retained by a ribbon (21) on blade members which holds together the sheet, the device and the bouquet, the sheet providing water-tightness to the device (8). Water (10) introduced into the device collects at its base (2), thus providing stability to the bouquet and converting the device into a disposable flower-pot. In the same way, a cylindrical sleeve (20) provides for the transport, by air or by road, with very little water, of a bunch of 40 flowers from the producing country to a buyer country.

Title: Remote access apparatus and method which allow dynamic internet protocol (ip) address management
Inventor: FEINSTEIN MICHAEL G
IPC: H04L29/12
Filed: 1996-04-04
Abstract: A user at a remote computer is provided access to a computer network by a remote access device coupled to the network. The remote access device receives from the remote computer a username which uniquely identifies the user on the network. The remote access device then obtains an Internet protocol (IP) address from a server on the network, which server dynamically assigns the IP address based on the username. The IP address uniquely identifies the remote computer on the network, and it is needed by the remote computer to communicate on the network. If the user at the remote computer disconnects, or is disconnected, from the network and then subsequently attempts to re-gain access to the network by sending the same username to either the same or a different remote access device coupled to the network, that remote access device obtains the same IP address from the server. The user at the remote computer thus is provided with the same IP address by the server on the network when the user disconnects and then later reconnects to the network even if each of the two connections is via a different remote access device.

Title: Method and apparatus for reforming grouped items
Inventor: MARKMAN HERBERT L
IPC: G06Q10/08
Filed: 1996-06-06
Abstract: Articles (24) such as garments to be cleaned are associated in a group (26) (e.g., one customer's order). After processing together with articles (24) from other groups (26), the articles (24) are to be reassembled in their original group units. Coded labels (32) are attached to each of the articles (24) and identify or are cross-referenced to its group (6), e.g., with barcodes (34). If articles (24) with permanent labels (32) are processed, group codes are assigned and stored for such articles (24), indexed to the permanent label information. Other articles (24) are each labelled as to their group (26). The total count or number of articles (24) in each group (26) is recorded, preferably on the article labels (32) but also possibly in a data memory accessible to a data processor (44) coupled to a scanner (70). For manually regrouping the articles (24), a scanner (70) is used and the group (26) identification is determined as articles (24) are encountered. The data processor (44) assigns and indicates visually one of a number of assembly locations (84) to be used temporarily to store the articles (24) for each group (26). As the articles (24) are scanned and manually placed, they are counted. The data processor compares the current count with the total for that group (26), and signals when the group (26) is complete, whereupon the location (84) can assemble another group (26). The device can be coupled to an inventory control system or operated as a stand alone unit, particularly if the number of articles (24) in each group (26) is recorded on the label (32).

Title: Run-length encoded image rotation
Inventor: MOED MICHAEL C
IPC: H04N1/41
Filed: 1996-07-24
Abstract: The inventive method and system includes a high speed computer algorithm (30) for rotating images stored in a memory of a computer (26), such as those captured by a CCD camera (22). The present invention is usable with on over-the-belt optical character recognition (OCR) reader (10) that captures a pixelized image of the surface of a parcel (14) as it moves along a conveyor (12). The preferred embodiment provides a method and system for obtaining a run-length encoded output image from a run-length encoded input image, wherein output image (17') is a rotated version of the input image (17). A predefined pixel mapping sequence for a rotation angle with a rational tangent is used to map image pixel data. Mapping image pixel data using a predefined pixel mapping sequence allows rotation without floating point computations, and allows the use of a reverse pixel mapping technique to map output runs from an input image in order to avoid the creation of holes or artifacts in the output image. The inventive method scales mapped output runs to preserve the aspect ratio of the rotated image. The inventive method selects the order in which to process the elements of the input run-length input table so as to directly create a run-length encoded output table.
